I have a MySQL DB (ClearDB) serving my backend application hosted on Heroku. That said I have very limited ways to actually see the logs (no access to the logs apparently) to even know what these queries are. I know for sure nobody is using the system right now. On my heroku logs there's really nothing being executed by the backend to trigger any query. What I can see from MySQL Workbench when looking at Status and Variables is that the values of Queries and Questions increase by the hundreds every second when I refresh it, which to me seems really odd. The value of Threads_connected is always between 120 and 140, although Threads_running is usually lower than 5.
The "Selects Per Second" keep jumping between 200 and 400.
I am mostly a developer with not much skills in being a DBA. Are these values normal? Even when there's no traffic why are they constantly increasing? If not, what are the means I can use to investigate what is actually running there when ClearDB does not give me access to logs?
'show processlist' can only raise my suspicion that something seems off, but then how to procedure from here?
